Pros
Office experience. If you are coming from a retail environment or do not have a college degree this is a good place to start building your resume. The work is not challenging at all but the payment processing industry is such a mystery to most people it looks good on a resume and you can make it sound great in an interview. If you are in the call center expect to take 4 - 8 inbound calls per hour. Plenty of time to read. Benefits are okay. People are okay. Food is okay. Gym is okay.
Cons
Can't use your cell phone at your desk. Outsourcing. Low pay. Cliques. Head scratching procedures. Slow computers. Poor communication between departments. Angry customers. HR is terrible. The coffee sucks. It's an evil company in an evil industry.
